Hi, I identified the patch that causes the Ada bootstrap
failure on x86 and x86_64 (at least):
../../xgcc -B../../ -c -g -O2 -fPIC -W -Wall -gnatpg s-stratt.adb -o
s-stratt.o
+===========================GNAT BUG DETECTED==============================+

* rtl.h (validate_subreg): Declare.
* emit-rtl.c (validate_subreg): New.
(gen_rtx_SUBREG): Use it.
* simplify-rtx.c (simplify_subreg): Likewise.
(simplify_gen_subreg): Likewise. Remove duplicate asserts.
* expr.c (emit_move_insn_1): Tidy complex move code. Use memory
fallback whenever gen_realpart/gen_imagpart would not be able to
create SUBREGs.

Should be fixed by:
2004-11-26 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
* expmed.c (extract_bit_field): When extracting from non-integer mode,
force a SUBREG into a register because we may be taking a further
SUBREG of it.
Testing on ppc-darwin right now.
